Be it known that I, DAVID V. KAUFMAN, a citizen of the United States, and a resident of the city of New York, borough ofManhattan, in the county and State of New York, have invented a new and Improved Ink Distributor, of which the following is a full, clear, and exact description.

This invention relates to printing presses and particularly to an improved attachment therefor, and has for an object to provide a construction which may be bodily applied and removed at any time without injuring the attachment or the press. 7

Another object-inview is to provide an improved ink distributing construction whereby all parts of a sheet may be supplied with substantially an evensquantity of ink and thereby cause pictures and other, representations requiring an appreciable amount of ink to all appear alike when printed.

, A further object of the invention is to provide an attachment for printing presses which may be readily applied and removed at any time and which isconstructedwith one or more distributingrollers adapted to engage one or more of the permanent ink distributing rollers of the press andcon- .tinually act as distributing members for distributing ink over .said permanent rollers during the operation of the. press.

An additional object is; to provide an attachment for printing presses having one or more distributing rollers which reciprocate as they rotate. a Y

some form of inking device is provided which will automatically ink the'type. In order that the, ink may be properly dis tributed over the surface, it has become the I practice to provide two ormore distributing rollers,.somet1mes acting alone and other times-in connection with auxiliary meansfor] securing eflicient inking of the type. In the present invention, means have beenv provided which are'designed to be readily attachedor removed at any time and to assist the or? dinary ink rollers now in use in providing an even distribution at all times without supplying ink in too large quantities. I v

In Figures 1,2 and 3 one construction of attachment is shown which is particularly adapted for a, certain type ofpress having a comparatively large bar 1 forming part of the distributing mechanism which mechanism also includes .the distributing rollers 2, 3' and 4C. These members are all now in common use and form no part of the present invention. In order that applicant.s rollers or dist-ributing members 5" and 6 may properly function they are carried'byend frames 7 and 8," each of said frames. having a bifurcation 9 as shown in Figure 2 whereby the bar -1 maybe readily 'straddledand the device clamped thereto by one more set screws 10. These set screws are preferably locked by suitable nuts 11. whereby the de vice may be held rigidlyin place andthe rollers 5 and 6 in contact with the respec tive rollers 2, 3 and 4. Each of the frames 7 and 8 is provided Witharms 12-and l3-and with a rounded depending nose 14 designed to permit the' device to slide overanyobstruction in case there is a slight swinging movement of'the parts during rapid opera tion of the press. The arms 12 and 13.131'6 each provided with agroove 15 in which a'bearing' box 16 is slidingly mounted, said box having fiat upper and lowersides and a round aperture for-receiving the rounded, projection 17 extending from the hubblock 18, which hub block is round and over which the end of the respective tubes extend. Suitable rivets or other securing members 19- actto connect the rollers to their hub blocks-18; A pin 20 (Figure 3) .ijs connected with, each of the bearing boxes, 16 and 12 and 13 by suitable pins or screws 22 whereby the rollers 5 and 6 are resiliently held against the rollers 2, 3 and 4. Therefore, whenever the rollers 2, 3 and 4 are rotated as they act in their usual capacity, the friction and adhesive quality of the ink will cause the rollers 5 and 6 to also rotate and continually distribute over rollers 2, 3 and 4 ink, said ink being taken off of the rollers 5 and 6 to supply shallow spots on the rollers 2, 3 and 4 and in turn the rollers 2, 3 and 4 supply ink to the rollers 5 and 6. This is of great advantage where more than one picture is to be printed on a single sheet and especially where said pictures are in alinement. If the rollers 5 and 6 are not used the first picture would take up most of the ink on the rollers 2, 3 and 4 as said rollers pass thereover so that a less quantity would be provided for the second picture and, consequently, the second picture would be lighter than the first when printed. lVhen the rollers 5 and 6 are used, said rollers will supply the deficiency in ink and, consequently, provide ample ink for the second picture. In printing ordinary type the same is used though less noticeable as the type to first receive the ink will naturally receive the most ink and asthe rollers pass over the type less and less ink will be supplied. lVith an attachment which includes the rollers 5 and 6 all of the type are supplied with the same quantity of ink and, consequently, the printers sheet will appear the same color throughout.

In case it should be undesirable or unnecessary to use the attachment, the same may be easily and quickly removed by loosening the set screws 10 and bodily lifting the device oil of the press. This will leave the press in its usual shape or condition so that it may function in its usual manner. At any time the device may be again placed on the press without altering the press or the device.

In Figures 4 and 5 a slightly modified form of the invention is shown which embodies the same inventive idea as shown in Figure l but which is designed particularly for a different type of press or rather with a different type of distributing mechanism. As indicated in Figure 5 the distributing mechanism to which the structure shown in Figures 4 and 5 is to be used carries transverse rods or bars 23 and 24 and distributing rollers 25, 26, 27 and 28. Each of the frames 7 and 8 is provided with two bifurcations 9' and instead of having a set screw 10 a single pin 29 is used for each frame, said pin "loosely fitting in suitable apertures in the projections forming the bifurcation 9. However, these apertures are so positioned that the pin 29 will snugly fit against the bars 23 and '24 and hold the frames comparatively rigid. In this form of the invention the rollers 5' and 6' are each arranged to contact with two of the regular inking rollers of the press. In addition, these rollers reciprocate as they rotate. It-is, of course, evident that the rollers 5 and 6 in the preferred form of the invention may reciprocate also.

As shown in Figure 4 each of the rollers 5' and 6 is loosely mounted on the hub blocks 18 and carry a pin 30 which preferably carries a roller 31 fitting in a spirally arranged groove 32 in the tubular member 33, which tubular member is riveted or otherwise rigidly secured to the shaft 34. The shaft 34 at the ends is provided with flattened sections 35 fitting into the respective bearing boxes 16 whereby said shafts may move laterally in the grooves 15 but cannot rotate. As the shells or rollers 5 and 6 are rotated by contact with the respective rollers 25, 26, 27 and 28, the action of the pin 30 and associated parts on member 33 will cause a reciprocation of the rollers 5' or 6 as the case may be. This reciprocation during rotation acts to more thoroughly distribute the ink especially where there is only one distributing roller on the attachment for two of the rollers on the printing press.

In Figures 6 and 7 a third form of the invention is shown which is really a slight modification from that shown in Figure 4. In this form of the invention each of the frames 7 and 8 is provided with a single bifurcation 36 for receiving a small rod 37 forming part of the ink distributing mechanism of the press, which ink distributing mechanism also includes the rollers 38, 39, 40 and 41. Where the press is provided only with one small rod 37 to which-the device may be attached, preferably two set screws 42 and 43 are used on each of the frames, said setscrews being arranged to engage the rod 37 at opposite sides of a vertical central line whereby a good pinching action is secured and the device is prevented from any independent swinging movement. Aside from this adaptation of the invention to the particular press the detail construction is identical to that shown in Figure 4 and, therefore, will need no additional description. It may be stated, however, that the frames in this form of the invention as well as the frames in the formshown in Figure 4 may be provided with any desired number of bracing bars 45 and 46 for holding the frames in proper position.

What I claim is 1. In an ink distributor for printing presses, a hinged supporting frame, rollers carried by said frameand-adapted to engage the distributing rollers of the press, means for 'removably connecting said frame to'ithe printing press, said rollers reciprocating in a direction transverse to the direction of the against the distributing rollers, said rollers and said frame being attachable on said press as a unit.
